A new cast detection approach based on image analysis was presented to overcome the limitations of conventional algorithm. The color colorfulness index(CCI) was adopted to optimize the calculation of cast factors by CCI weighting. The images containing simple colors were converted into colorful images to eliminate the influence of dominant color on color cast detection and decrease the misjudgment ratio. Compared with traditional algorithm, the results showed that the new technique could detect cast images accurately and efficiently, while enhance the detection accuracy and reliability. Compared with the results of subjective evaluation, this approach could eliminate the influence of dominant colors, reduce the misjudgment rate of color cast images, and precisely identify color cast images and dominant color images.
